[0018] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and should not be construed as limiting the present invention.

[0019] First embodiment

[0020] See also Figure 1 and Figure 2 , Figure 1It is an overall structural diagram of the sectional fire truck side folding stairs of the first embodiment of the utility model. Figure 2 It is a projection diagram of the side folding stairs of a sectional fire truck according to the first embodiment of the utility model.

[0021] The utility model provides a sectional fire truck side folding staircase: comprising a base 101, a staircase main frame 102, a reinforcement component and a telescopic component, wherein the telescopic component comprises a mounting plate 103, a folding block 104, a telescopic extension frame 105 and a limiting member, wherein the limiting member comprises a limiting block 106, a locking indexing pin 107 and a buckle 108. The above solution solves the problem that the climbing ladder cannot be folded. It can be understood that the above solution can be used to avoid the situation where the whole vehicle is too long, and can also be used to solve the problem that the stairs are not stable enough.

[0022] In this embodiment, the main stair frame 102 is fixedly connected to the base 101 and is located on one side of the base 101. The base 101 is a rectangular seat, which is arranged on the fire truck body. The main stair frame 102 is composed of a ladder frame and a ladder board, and the main stair frame 102 is fixedly arranged above the base 101.

[0023] Among them, the mounting plate 103 is fixedly connected to the stair main frame 102 and is located on a side of the stair main frame 102 close to the base 101; the folding block 104 is rotatably connected to the mounting plate 103 and is located on a side of the mounting plate 103 close to the stair main frame 102; the telescopic extension frame 105 is fixedly connected to the folding block 104 and is located on a side of the folding block 104 close to the stair main frame 102; and the limiting member limits the telescopic extension frame 105. The mounting plate 103 is a rectangular plate, there are two mounting plates 103, which are fixedly connected to the main body frame and symmetrically arranged on the outer side of the ladder frame of the stair main frame 102. The folding block 104 is a rectangular block, which is rotationally connected to the mounting plate 103 through a roller and is arranged on the outer side of the mounting plate 103. The telescopic extension frame 105 is fixedly connected to the folding block 104 and is arranged on the outer side of the folding block 104. The limiting member limits the telescopic extension frame 105. The telescopic extension frame 105 is folded by folding the folding block 104 on the mounting plate 103. The telescopic extension frame 105 can be folded during driving, thereby avoiding the risk of the vehicle being overlengthened.

[0024] Secondly, the limit block 106 is fixedly connected to the mounting plate 103 and is located on the side of the mounting plate 103 close to the folding block 104; the locking indexing pin 107 is slidably connected to the limit block 106, abuts against the folding block 104, and is located on the side of the limit block 106 close to the folding block 104. The limit block 106 is a rectangular block, which is fixedly connected to the mounting plate 103 and is arranged at the end of the mounting plate 103. The locking indexing pin 107 is a pin body with an external thread. The locking indexing pin 107 is screwed into the limit block 106 and screwed into one side of the limit block 106 to extend into the folding block 104, thereby achieving abutment against the folding block 104. By rotating the locking indexing pin 107, the folding block 104 is locked on the limit block 106, thereby limiting the telescopic extension frame 105.

[0025] Again, the buckle 108 is arranged on the main stair frame 102, and fastens the telescopic extension frame 105, and is located on the side of the main stair frame 102 close to the telescopic extension frame 105. The buckle 108 is made of stainless steel, and the buckle 108 is arranged at the bottom end of the main stair frame 102. The buckle 108 locks the telescopic extension frame 105, thereby preventing the telescopic extension frame 105 from flipping over during the driving of the vehicle.

[0026] When using the sectional fire truck side folding staircase of the utility model, the telescopic extension frame 105 is folded by folding the folding block 104 on the mounting plate 103, and the telescopic extension frame 105 can be folded during driving, thereby avoiding the risk of the entire vehicle being too long. The buckle 108 locks the telescopic extension frame 105, thereby preventing the telescopic extension frame 105 from flipping over during vehicle driving. The locking indexing pin 107 is rotated to lock the folding block 104 on the limit block 106, thereby limiting the telescopic extension frame 105, and thereby keeping the telescopic extension frame 105 stable when extended.

[0027] Second embodiment

[0028] See also Figure 3 and Figure 4 , Figure 3 It is an overall structural diagram of a sectional fire truck side folding staircase of a second embodiment of the utility model. Figure 4 It is a projection diagram of the sectional fire truck side folding staircase of the second embodiment of the utility model. On the basis of the first embodiment, the reinforcement assembly includes a reinforcement bracket 201 and a stabilizing member, and the stabilizing member includes a connecting seat 202 and a stabilizing support rod 203.

[0029] The reinforcing bracket 201 is fixedly connected to the stair main frame 102 and is located on a side of the stair main frame 102 close to the base 101; the stabilizing member is respectively connected to the base 101 and the reinforcing bracket 201. The reinforcing bracket 201 is a U-shaped bracket, and the reinforcing bracket 201 is fixedly arranged on the stair main frame 102. The stabilizing member supports the reinforcing bracket 201. Through the supporting effect of the reinforcing bracket 201 and the stabilizing member, the stair main frame 102 is more stable.

[0030] Secondly, the connection seat 202 is fixedly connected to the reinforcement bracket 201 and is located on the side of the reinforcement bracket 201 close to the base 101; the stabilizing support rod 203 is fixedly connected to the connection seat 202 and is fixedly connected to the base 101 and is located on the side of the connection seat 202 close to the base 101. The connection seat 202 is a rectangular seat, which is fixedly arranged on the outside of the reinforcement bracket 201. The stabilizing support rod 203 is a rectangular rod, which is fixedly connected to the connection seat 202 and the base 101 respectively, and is obliquely arranged between the connection seat 202 and the base 101. Through the supporting effect of the connection seat 202 and the stabilizing support rod 203, the connection between the reinforcement bracket 201 and the base 101 is more stable.

[0031] When the sectional fire truck side folding staircase of the utility model is used, the connection between the reinforcing bracket 201 and the base 101 is more firmly connected through the supporting effect of the connecting seat 202 and the stabilizing support rod 203, and the main stair frame 102 is further stabilized through the support of the reinforcing bracket 201.

[0032] The above disclosure is only a preferred embodiment of the present invention, and certainly cannot be used to limit the scope of rights of the present invention. Ordinary technicians in this field can understand that all or part of the processes of the above embodiment and equivalent changes made according to the claims of the present invention still fall within the scope covered by the utility model.
